양방향에서 접근하는 이동하중을 고려한 단순보의 동적거동

초록

This study focuses on dynamic behaviors of simply supported beams, especially, vertical displacements. Based on moving load model, the displacement is estimated by response superposition. The displacements tend to increase as load velocity increases except under resonance velocity and show very large values under resonance velocity. Therefore, we should investigate the resonance between train and structure.
